Abstract
The invention relates to a door for a railway vehicle, intended for a door opening having steps, on which there are provided a platform and a threshold above the steps to permit disembarking onto a railway platform situated higher than the steps. The invention is characterised in that the door includes a single leaf and a mechanism provided for controlling the unlocking of the threshold member with respect to the door, when the platform is in the position of use and the door opens, so that this threshold member remains in place opposite the edge of the platform in the position of use and the edge of the railway platform.
